Abstract
Systems and methods include using a magnetic core winder to install a powerline-mounted device with a non-gapped magnetic core, therefore reducing the weight of the powerline-mounted device while still harvesting equal or more power than a large cross-sectional and gapped magnetic cores. In particular, the methods include installing bobbin(s) and a core housing on a powerline and winding strip/ribbon core material onto the core housing. The bobbins may be wound axially opposed to on a toroid winder, which improves the accuracy of turns count of the magnetic core. The improved accuracy of turns count may increase the accuracy and/or tolerance of magnetic component(s) of the powerline-mounted device.
Claims27
A device configured to be mounted on a conductor of an electric power delivery system, comprising:
- a spool configured to store magnetic core material;
- and
- a hinged core casing configured to be clamped around the conductor, wherein the hinged core casing is coupled to the spool and configured to rotate to cause the magnetic core material to be extracted from the spool and wind around the hinged core casing to produce a non-gapped magnetic core.
A system, comprising:
- a device configured to be installed on a conductor of an electric power delivery system, comprising:
- a transformer configured to harvest electric energy from a magnetic field produced by the conductor, comprising:
- a non-gapped magnetic core;
- a core casing configured to enclose the non-gapped magnetic core;
- one or more bobbins mounted on the core casing, wherein the one or more bobbins are wound with conductive material forming a secondary winding;
- and
- a spool configured to store magnetic core material;
- an interface device configured to connect a utility tool to the device to facilitate installing the device;
- and
- a wireless control device communicatively coupled to the interface device and configured to remotely control operations of the interface device.
A method for installing a transformer around a conductor, the method comprising:
- placing an openable core casing around the conductor;
- closing the openable core casing;
- and
- winding a core material around the openable core casing to produce a non-gapped magnetic core of the transformer.
A method for installing a transformer around a conductor, the method comprising:
- bending an axial bobbin around the conductor to form a toroid winder;
- and
- winding a core material into the toroid winder to produce a non-gapped magnetic core of the transformer.
